TAKING GAS ANALYSIS OUT OF THE LAB AND ON THE ROAD
Gas analysis just got a lot less complicated. Apix Analytics’ multigas analysis system
can determine the composition of a gas sample at the sample collection point and
without the need for cumbersome lab equipment. The analysis is just as accurate as
traditional lab testing, but at a dramatically lower cost.
Apix Analytics’ silicon-based labs-on-chip
are much more compact than traditional
lab testing equipment. The technology
was invented by Leti and Caltech and is
undergoing further development work at
a joint Leti-Apix Analytics lab.
The labs feature a miniature chromatography
column machined on silicon to separate the
gases in the sample. The gases are then
detected by nanoresonators that vibrate
at a given frequency. The surface of each
nanoresonator is covered with a chemical
layer that promotes the adsorption of
molecules. When the gas molecules are
deposited onto the surface, the resonator’s
mass increases, and its vibration frequency
changes. This information is used to
determine the concentration of each
component in a gas sample.
Apix Analytics is the first manufacturer to
offer nanoresonator-based gas detection
capabilities—crucial to ensuring sensitivity
